MIDI Agent

Type a prompt in plain language, such as a chord progression or a melody idea, and MIDI Agent returns MIDI you can drop straight into your DAW.

MIDI Agent is an AI MIDI generator that runs as a VST/AU plugin, so the results appear inside the session you are already working in rather than in a separate web app.

It connects to several language models, including ChatGPT, Claude, Gemini, DeepSeek and Grok, and you can pick which one writes your parts.

Output covers melodies, chords and full compositions.

The plugin also transcribes MIDI and audio files and can expand existing material, which helps when you have a rough idea and want it developed instead of starting from nothing.

Flexible API options mean you can bring your own model access, and the plugin works with major DAWs.

If you think in text prompts more than in piano roll clicks, MIDI Agent fits that habit well.

Results depend on the model you choose and how clearly you describe what you want.
